[Kenwood] Re: [VHF] Kenwood interface

Hi Tom,
The interface is a box containing a level shifter chip (Maxim MAX232-C), 
some miscellaneous transistors, resistors and caps, and a couple of 
connectors. They can be had at flea markets, often for 40ドル-75. They have 
been out of commercial production for years.
One alternative is to build your own, which is what I did recently. There 
is an article on the project in the Feb. 1993 QST. A kit is available from 
FAR circuits which contains the printed circuit board, the 232 chip and the 
opto-isolators. The only parts I added to that were four resistors, several 
caps, a voltage regulator, some wire, two connectors, a grommet and a small 
metal chassis. All that is available at Radio Shack. My project worked the 
first time when connected to my TS-790. I built a second one for my TS-850, 
which also checked out the first time (on the 790, the 850 is on the blink 
right now due to an unrelated fault).
I can send the QST article via E-mail if you like (Adobe .pdf file), and 
some pics of my interface if that would help.
Also, the original Kenwood interfaces show up for sale on eHam.net, QRZ.com 
and QTH.com from time to time, often with pictures.
